brushes now in common use.

Another object is to provide a-cotton gin,

wherein the lint will be transferred through the lint flue to the condenser by the agency A further Ob ect' [S to provide the most etlicient means for removing the lintfrom the saws, by the agency of compressed air,

and for separating at thesame time motes and trash from the hut.

Finally the object of the invention i's to provide a device of the character described,

that will be strong, durable. simple, and efficient, and comparatively easy to produce. and also one in which the various parts will not be likely to get out of working order.

\Yit'h these. and various other objects in view, my invention has relation to certain novel features of construction andoperation, an example of which is described in the fol lowing specification and illustrated in the ac companyiiig drawings, whercii'i Figure-.1 is adiagrainmatic plan view of. a two gin outfit, including the lint flue, the condenser, air compressing means. and a compressed air distribution system. Fig. 2

is a perspective view of the condenser and a portion of the hut flue, showing how compressed air is'introduced into these parts to produce a blast ahead of the lint. Fig. 3 is a cross section through the lint flue on the line of Fig. 1. .Fig. 4 is a detail sectional view of the extremity of one of the numerous small pipes, which blow the lint from the saws, showing how the outlets of these pipes are flared in order to spread the air as it is ejected. Fig, 5 is a cross sectional view of a gin stand, showing thecompresscd air feeder pipe sectionally, and the branch whereby the feeder may be elevated in order to regulate the angle at which the air blast. impinges upon the saws. Fig. 6 is a" top viewof a portion of a saw cylinder, showing pipes in elevation, "meansalso being shown the compressed air feeder adjacent thereto, and the numerous branch pipes projecting from the feeder between. the saws. i-

iteterrizu, now more particulatiy to the drawings wherein like numerals of reference designate similar parts in all the figures. the.

numeral 1 designates the gins, 2 the lint fiuc and 3 the condenser.

g Air is compressed .in the cylinder -'l by mcans'of the steam cylinder and is' brought to the required. pressure for use in the tank-6. From thistank, a distribution main extends behind the gins, supplying air to the tceders 8,within said gins. The

connections 9 between the main and the feeders are to be flexible for reasons hereinafter explained. From the feeders, there extend a plurality of small discharge pipes 10, having-their outlets'above and between the gin.

saws, and directed rcarwardly at an angle such that the air blast and lint will impinge upon the mote board 11. Means are described hereinafter for. creating a partial vacuum in the passage way 19 above the mote boardand leading to the lint. flue, so that the air blast from the pipes-1t) tends to turn rearwardly into said passageway car-' rying the lint from thesaws thereinto. Any

motes or-particles of trash that are' nixed with thedmt. and are heavier than the same will not,be sustained by the air blast. but will fall into the space 12 -whence they may be. removedby any suitable means. i

It is desirable that the angle at which the air blast impinges upon the saws be capable of some slight adjustment. and to secure this,

the lever 13 is provided. This lever has its.

lower extremity projecting beneath the.

feeder 8. so that by manipulating the lever,

the feeder may be displaced vertically to some extent. Since the-upper portion of the dischargepipes It) arerestricted from vertical motion by the board 1-1. the feeder must rotate slightly as it is raised, thus varyingthe discharge angle of the outlets. A curved rack 15 is provided to act in conjunw' ;tion with the usual-spring pressed rod and hold the lever in any desired position of ad justment. Transverse adjustment of the mote board may be accomplished by'meaus of the adjusting screw 16, rotatingin the lugs 17, the rear extremity of the screw being threaded into the rear lug. In order topermit of the vertical adjustment of the feeders 8, it is-necessa'ry that the'prevlously described connections 9- be flexible. By

making the extremities of the discharge v,pipe's '10'bell 'mout-hed asshownin Fig. 1-,

,the air is caused to .spread'out; immediately -upon-1tsescapetrom said pipes, -sweeping 6 ,clo se'i-to the saw surfaces 'so as" to' "act with a L maximum force upon the lint. From the feeder-pipe.
